That should probably be a separate patch since there are only two labels in the function I am touching here. I'll whip up a v2 if the maintainers want it though or I'll just draft a separate patch when I am done addressing all of the misleading indentation warnings. Thanks for the reply! Nathan

AFAIK those are intended to be there. Having labels indented by a space makes diff not believe those are function declarations. So a patching a function with a label won't show the label, but the function in the diff block header. Juergen
